This inventionrelates to improvements inslicing machines, of the type in which t is slicing knife is supported and carried by a swinging arm, and one of the objects of the invention is to provide'improved means for stacking the slices as they are out, without damage to the slices, and-while maintaining them against fold- Another object is to provide a swinging arm type of machine of this character, in which stacking meansiscar-ried by the arm for movement therewith and with respect thereto.

A further object is to provide an improved rotatablestacking device that is carried by. the arm, the rotary movement ofthe stacking device with'respect to the arm, being responsive to the swinging movement of the arm.

A stillfurther object is to provide an improved stacking, device which is readily attachable to, and detachablefrom, the swinging knifc-carrying arm.

Still another object is teprovide improved stacking device of this character, which is simple, durablecheap and compact in construction, and eifective and eiiicientin operation.

To. the. attainment of these ends, and the accomplishment ofother new and useful objects as will appear, the invention consists in the features of-..novelty, insubstantiaily the construction, combination and. arrangement of the several parts,

hereinafter more. fully described and claimed, and shown in theaccompanying drawingillustrating this invention, in-which Fig. 1 is a side elevation of a slicing machine of this character, having a stacking device con- Theslicingmachine consists essentially of a supporting base Id, of any desired or suitable size .andconstruction, and connected thereto is an armvor bracket H, which carries an. article or food holder or support 52, uponwhich. i'sslidably and adjustably mounted, a clamping device l3, all of a well-known construction, and which is adapted to be advanced with respect to the support in any suitable manner, to position the foodor article 14 that is to be cut, into the.cnt' ting plane of a rotatable slicing knife it? Mounted upon a suitable bracket it carried by the base i0; is a motor housing i'i, andsupported by the motor housingv and mounted't'o swing on an inclined axis, is an arm '33; which carries the rotary slicing knife. Suitable. mechanism (not shown) is providedto form a driving connection between the motor and the knife is, to rotate the latter in the proper direction. A handle i9 is provided, by means of which the arm iii may be swung about its pivot, while the knife is being rotated, to cut slices from the stock'or article I41 The article it is intermittently advanced as the slices are cut therefrom, in any suitable manner.

As the slicesZ'UiFig. 3) are out, they suedelivered t'oa receiving table or support 21', which is intermittently lowered as the slices are piled thereupon, in any, suitable manner well known in this. art, and diagrammatically illustrated at 22, 23. In order to stack the slices upon the receiving, table or support as they are cut, and to prevent them from folding, there is provided areceiving and guide member 2'4,which is preferably conical in shape, and the periphery of which may be either smooth or undulated. This member 24 is provided with a shaft 25', which isjournaledina, bearing 26, on a plate or mem ber 21; which in turn ismounted upon a stud 23 carried by the arm 98; The plate 2! is provided with an aperture 29 (Fig. 4), to receive the stud.

The plate 21 is alsoprovidedwith two oppositely opening slots 5E3, which are adapted. to receive studs 3|, on the arm, when the plate .is rotated about the stud 28-"in1 the .proper direction. The studs, 3! maybe in the form of screws, whereby they maybe tightened" to clamp or' securely'hold the plate 2'!" locked to the arm [8. A handle 32 may beprovided to facilitate'the handling and shifting'of'the plate and the mech- :anism carried thereby, when the plate-is manipulate'd;

Rotatably supported by the plate 2*]; is a roller 33, which is in driving connection with the guide member 24; in any; suitable manner;-' such as by means of a flexible shaft or-connection 34; wherebywhen the roller 33is rotated,1th'e'guide mem er 24 will also be rotated.with'respect to the arm I 8; Whenthe plate attachedxtothe arm 18,, the carrier .or guide member Z 'l 'wiihbe in a; position that the apex' end" thereof will" be lowermost, and the carrier will be disposed in proximity to the cutting plane of the knife, but will be spaced a sufficient distance from the knife so that as and when the slice is cut, it will fall upon the guide member (Fig. 3), and as the guide member is being rotated, the slice will be delivered to the receiving table or support 2|.

The motor housing ll is provided with an enlarged circular portion 35, encompassing the pivot of the arm l8, and is frictionally and tractionally engaged by the roller 33, carried by the plate 21, so that as the arm is is swung about its pivot by the operator grasping the handle i9, the roller 33 will be rotated with respect to the stationary plate 27, which will in turn,

. through the medium of the driving connection 34, rotates the guide member 2:3 about its longitudinal axis. The slices, as they are cut by the knife, will be delivered to, or will fall upon the guide member 2 and will be delivered to the slice receiving support 2! in a flat condition, to be piled thereupon, and they will be prevented from folding or breaking.

When it is desired to remove the guide member 24 for cleaning or for any other purpose, this may be readily accomplished by grasping the handle 32, and rotating the plate .i'i about the stud 28 on the arm I8, in a direction to cause the recessed portions 30 of the plate to disengage the studs 3|, whereupon the plate 2?, the guide member 24, and the driving roller 33 may be disengaged, as a unit, from the arm I8.

If desired, and if the surface of the guide member 24 is grooved or undulated, a scraper device 36 (Fig. having fingers 3?, may be provided and mounted upon the plate 2?, so that the fingers Will extend into the grooves 38 and, by a camming action on the slices issuing from the knife 15, transfer them to the receiving support 2! If desired, the rotatable guide member 39 may be of a sectional construction, that is, divided into a plurality of rotatable sections 49 and 4! (Fig. 6). The section 4! is mounted on and adapted to be driven by a shaft 43 while the section 40 is mounted on and adapted to be driven by a sleeve shaft 32 surrounding the shaft 33. The shafts 42 and d3 may be driven in any suitable manner (not shown). It will be noted that because the two sections so and ii are driven at different rates lfa of rotation, there is little tendency for the slices to adhere to the guide member as a whole.

It will therefore be manifest that the guiding or stacking device may be readily appli d to, and

detached from, the arm l8, and the machine may be effectively operated either with or without the attachment of the stacking device. When used, the stacking device may be readily and quickly detached for cleaning purposes, and may be as readily attached for use.

While the preferred forms of the invention have been herein shown and described, it is to be understood that various changes may be made in the details of construction, and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
